Build A Walkway Pergola
Make the most of a large backyard and extend your outdoor living area with a shaded seating area with a pergola over a pathway.
The main posts of this treated-pine pergola are anchored in concrete. Make the post holes 400mm deep and 300mm wide, spaced 1350mm apart for the front and back, and 1050mm for the sides.
The frame is constructed the old-fashioned way, with tenons and housings cut into the timber with a circular saw and handsaw. It’s easier to apply the first coat of stain while the components are flat on the ground.
Keep the stain handy throughout assembly to apply on all cut ends and inside joints.
- Arbour A stand-alone lattice framework covered with vines.
- Pergola Covered, trellised area supported by columns or posts.
- Gazebo A small roofed structure screened on all sides.
Side beams are tenoned at each end to fit mortices on the posts.
Cut the beams to 1080mm and square a line around each end, 70mm in. Mark the tenon on each end with a marking gauge set at 45mm.
Set a circular saw to 45mm and cut the shoulder with several relieving cuts across the beam from both sides. Remove the waste and clean up the faces of the tenon with a chisel.
Bird’s mouth cut
Use a sliding bevel set the same as the plumb cut at the top of the rafter and transfer the angle to the measurement in Diagram 6.
Cut the bird’s mouth with a circular saw, stopping at each set-out line. Remove waste by completing with a handsaw.
Check the fit of the rafter at each location and note any adjustments before setting out remaining rafters.
For strength, fix a metal joint connector on the inside face of the rafter and place a nail plate across the back of the rafter support post and each rafter (see Diagram 6).
